Heat, in some cases. The wearing away of objects.
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction is specific to the two materials, in this example the block of wood and the floor. In addition, there is a static coefficient of friction (applicable to a stationary situation) and a kinetic coefficient of friction (applicable when the object is already moving).

Friction plays a vital role in our daily life. Without friction we are handicap.1. It is becomes difficult to walk on a slippery road due to low friction. When we move on ice, it becomes difficult to walk due to low friction of ice.2. We can not fix nail in the wood or wall if there is no friction. It is friction which holds the nail.3. A horse can not pull a cart unless friction furnishes him a secure foothold.
Kinetic Friction replaces Static Friction when an object is in motion.
An example of undesirable friction is when a cyclists falls and his face against pavement that skin on the road. Undesirable friction is something that is not controllable.
False. Friction is not always undesirable. It is necessary for many everyday activities such as walking, driving, and gripping objects. However, it can also be undesirable in some situations like in machinery where it can cause wear and energy loss.
When one wants things to slide, move, or turn easily.
Pickle
A banjax is a mess or undesirable situation made as a result of incompetence.
Desirable in scrummaging when the two packs form together. Without friction they would slip off which is dangerous. Friction is also desirable when making the tackle. And when sidestepping you need good grip. Undesireable when trying to evade the tackle.
Friction can be increased in a given situation by increasing the roughness of the surfaces in contact, increasing the force pressing the surfaces together, or by using materials with higher coefficients of friction.
Friction between moving parts of a machine leads to energy loss in the form of heat, which can cause overheating and reduce the efficiency of the machine. It also causes wear and tear on the parts, leading to increased maintenance and replacement costs. Additionally, excessive friction can impact the accuracy and performance of the machine.
A car moving on a road - friction between the tires and the road slows down the car and decreases fuel efficiency. When using a pencil eraser - friction can cause the eraser to wear down quickly and potentially damage the paper surface.
Figuratively, a camel's nose is a metaphor for a situation where the allowance of a small act will lead to a larger, undesirable act.
It is best to reduce friction in machinery to improve efficiency and reduce wear and tear. Another situation is in sports like ice skating or skiing where reducing friction allows for smoother movement and faster speeds.
Friction can cause wear and tear on surfaces, leading to damage and reduced lifespan of objects. Friction can generate heat, which can result in overheating and damage to machinery or devices. Friction can impede motion, making it harder to move objects or causing inefficiency in mechanical systems. Friction can create noise and vibrations, which may be undesirable in certain applications.
